A self-testing application?

Actually, it’s a piece of an ETL pipeline that will run daily. And so I’d it to refuse to run if the input format has changed too much. It’s Haskell that I’m going to try implementing in Elixir: GitHub - public-law/nevada-revised-statutes-parser: Parses the Nevada NRS into well formed JSON · GitHub

My tests mostly run on fixtures which are full files: nevada-revised-statutes-parser/test/fixtures at master · public-law/nevada-revised-statutes-parser · GitHub
